Abstract
The invention discloses and provides a surface piercing propeller ventilation system which actively conducts inflation on a surface piercing propeller and promotes the circulation of air above the propeller so as to greatly improve the work efficiency of the surface piercing propeller. The surface piercing propeller ventilation system comprises a cabin, at least one power main engine arranged in the tail of the cabin, and a surface piercing propeller push device connected with the power main engines. Main engine exhaust pipes fixed into the cabin through exhaust pipe supports are communicated with the power main engines. The exhaust ports of the main engine exhaust pipes are located outside the cabin and arranged downwards in the mode that the exhaust ports are perpendicular to the horizontal plane. The arrangement positions of the exhaust ports are higher than the water surface all the time. When the surface piercing propeller push device begins running, the surface of the surface piercing propeller push device can make contact with air above the water surface, a large amount of air is consumed, the main engine exhaust pipes actively discharge air towards the surface piercing propeller push device at the moment, and the work efficiency of the surface piercing propeller ventilation system is improved. The surface piercing propeller ventilation system is suitable for the field of ship and boat manufacturing.
